Physical and lithological properties Oligocene-Miocene formations of the Okhotsk-Kamchatka Basin (to 85-th Anniversary of Professor Yuri Konstantinovich Burlin)

Abstract

The purpose of the investigation was the prediction of physical and lithological properties of volcanogenic-sedimentary formations at different depths. For this purpose Oligocene-Miocene sediments from a number of wells within the Icha and Kolpakovsky depressions of Okhotsk-Kamchatka oil and gas basin have been studied. Relationship between temperature and fluid conditions of the katagenesis zone and the change in the rocks composition, their porosity, permeability, density, thermal conductivity were identified. Superposed phenomena and characteristics of the reservoir rocks transformations within the water-hydrocarbon contacts in the gas and gas condensate pools have been considered. The relationship between volcanogenic-sedimentary rocks physical and lithological properties and the formation of non-stationary geothermal regime has been shown. The article is devoted to the head of these investigations – Professor Yuri Konstantinovich Burlin (1931-2011). 12 Oktober this year, he would have turned his 85 years.
